Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of automobiles, in particular to a vehicle door and a hidden door handle ice breaking method and device. BACKGROUND

[0002] With the rapid development of new energy vehicle technology, the proportion of new energy vehicle sales is gradually increasing, especially electric vehicles. Many intelligent technologies are continuously applied to electric vehicles, such as hidden door handle function and electric door function. The design of the hidden door handle function can reduce wind resistance, increase the sense of technology, and at the same time maintain the consistency and aesthetics of the styling, and increase the competitiveness of the styling. The design of the electric door function can realize automatic opening and closing of the vehicle door, which is convenient for the driver and passengers to get on and off the vehicle, and improves the sense of technology of the vehicle. However, in low temperature environment, especially in extremely cold weather environment, or after washing the car in cold winter, the phenomenon of ice formation between the vehicle door and the door frame will easily occur, which will cause the vehicle door to be unable to be pulled open, especially for vehicles equipped with hidden handles, the hidden handle will be frozen and unable to pop out, resulting in poor user experience. For this situation, many mechanical ice breaking mechanisms driven by motors have appeared, which realize the ice breaking function through the ice breaking mechanism. However, the installation of such ice breaking mechanism for ice breaking will produce a lot of noise in the ice breaking process, and the installation of ice breaking mechanism on the hidden handle or the vehicle door will cause the space inside the handle or the vehicle door to be tight, and at the same time increase the weight of the vehicle door, which is very cumbersome. SUMMARY

[0003] To solve the above problems, the application provides a vehicle door and a hidden door handle ice breaking method and device. The application controls the temperature through the introduction of temperature sensors and heating wires in cooperation with the vehicle door controller, and realizes the ice breaking function of the vehicle door and the hidden door handle in multiple ways through the cooperation of the BCM controller, the IVI entertainment host and the T_BOX. The ice breaking process is elegant, does not produce noise and mechanical deformation, does not increase the weight of the vehicle door, and occupies a small installation space.

[0004] The technical scheme of the application is described below in combination with the drawings:

[0005] In a first aspect, the application provides a vehicle door and a hidden door handle ice breaking method, comprising the following steps:

[0006] Step one, when the driver drives the vehicle for the first time, the average temperature of the hidden door handle, the door frame rubber sleeve temperature sensor and the door frame temperature sensor is lower than 0℃ after the ignition of the vehicle is turned on, that is, IG ON, the driver is notified;

[0007] Step two, the driver receives the notification and selects the automatic opening of the door and the handle de-icing mode or the manual opening of the door and the handle de-icing mode;

[0008] Step three, the driver opens the door and the hidden handle according to the selected automatic opening of the door and the handle de-icing mode or the manual opening of the door and the handle de-icing mode.

[0009] Further, in step one, when the average temperature of the hidden handle, the hidden handle temperature sensor, the door frame rubber sleeve temperature sensor and the door frame metal temperature sensor is lower than 0℃, the driver is notified through the instrument or IVI display.

[0010] Further, in step two, the driver manually opens the door and the handle de-icing mode through the external microphone voice or Bluetooth or remote key or mobile phone.

[0011] Further, in step two, when the driver selects the automatic opening of the door and the handle de-icing mode or the manual opening of the door and the handle de-icing mode, the driver can select the single door mode or the front two door mode or the four door mode.

[0012] Further, the specific method of step three is as follows:

[0013] a) When the driver selects the automatic opening of the door and the handle de-icing mode, the specific method is as follows:

[0014] When the vehicle is unlocked, the handle is popped up. If the handle is not popped up, it will be tried again after 1 second. If the handle is still not popped up, the vehicle door controller will obtain the environmental temperature information collected by the hidden handle, the hidden handle temperature sensor and the door frame rubber sleeve temperature sensor. If the average temperature is less than 0 degrees, the vehicle door controller will obtain the power supply information of the whole vehicle through the bus. If the power supply is too low, the driver will be prompted to perform high-voltage power supply for the battery. If the power supply is normal, the vehicle door controller will drive the heating wire in the hidden handle and the hidden handle to start heating. When the average temperature of the hidden handle reaches 4℃, the handle will be tried to pop up again. If the handle is not popped up, the heating will continue to 6℃ and the handle will be tried to pop up again. Then the heating will stop.

[0015] Regarding the opening of the door, if the vehicle is equipped with an electric door, the vehicle door controller drives the electric door to open. When the driving current is greater than 1.2 times the normal opening current value, the driving of the electric door is stopped, and the door frame rubber sleeve heating wire and the door frame metal heating wire are driven to heat. When the average temperature of the door frame rubber sleeve temperature sensor and the door frame metal temperature sensor reaches 4℃, the vehicle door controller drives the electric door to open again. If the door is not opened, the heating will continue to 6℃ and the door will be tried to open again. Then the heating will stop.

[0016] If the vehicle is configured with a traditional manually opened door, the vehicle controller drives the door frame rubber sleeve heating wire and the door frame metal heating wire to heat, and when the average temperature of the door frame rubber sleeve temperature sensor and the door frame metal temperature sensor reaches 4℃, the driver is reminded to manually open the door.

[0017] b) When the driver selects the manual door opening and door handle deicing mode:

[0018] After the whole vehicle is unlocked, the door handle is popped up, and if it is not popped up due to resistance, it is tried to pop up again after 1 second. If the door handle is not popped up, the vehicle door controller obtains the ambient temperature information collected by the hidden door handle temperature sensor, the hidden door handle temperature sensor and the door frame rubber sleeve temperature sensor. If the average temperature is less than 0 degrees, the driver is prompted to start the door opening and door handle deicing mode. After the driver starts the deicing mode, the vehicle door controller obtains the whole vehicle power supply information through the bus. If the power supply power is too low, the driver is prompted to perform high-voltage power supply for the battery. If the power supply power is normal, the vehicle door controller drives the heating wire in the hidden door handle and the hidden door handle metal heating wire to start heating. When the average temperature of the hidden door handle temperature sensor reaches 4℃, the door handle is tried to pop up again. If the resistance is encountered, the heating is continued to 6℃ and the door handle is tried to pop up again, and then stopped.

[0019] Regarding the door opening, if the vehicle is configured with an electric door, the vehicle door controller drives the electric door to open. When the driving current is greater than 1.2 times the normal door opening current value, the driving of the electric door to open is stopped, and the door frame rubber sleeve heating wire and the door frame metal heating wire are driven to heat. When the average temperature of the door frame rubber sleeve temperature sensor and the door frame metal temperature sensor reaches 4℃, the vehicle door controller drives the electric door to open again. If the resistance is encountered, the heating is continued to 6℃ and the door is tried to open again, and then stopped.

[0020] If the vehicle is configured with a traditional manually opened door, the vehicle controller drives the door frame rubber sleeve heating wire and the door frame metal heating wire to heat, and when the average temperature of the door frame rubber sleeve temperature sensor and the door frame metal temperature sensor reaches 4℃, the driver is reminded to manually open the door.

[0021] Further, in step three, the driver is prompted to perform high-voltage power supply for the battery through the APP or voice or Bluetooth.

[0022] Further, the driver is reminded to manually open the door through the horn, light double flash or external speaker or APP.

[0023] Further, when the driver selects the manual door opening and door handle deicing mode, the driver is prompted to start the door opening and door handle deicing mode through the APP or voice or Bluetooth.

[0024] Further, in winter, when the vehicle is remotely controlled by the mobile phone APP to perform air conditioning heating, the hidden door handle is synchronously remotely controlled to perform heating.

[0025] In a second aspect, the application further provides a vehicle door and hidden door handle ice breaking device, comprising a first temperature sensor arranged on a rubber sleeve of a door frame of the vehicle door, a second temperature sensor arranged at a metal plate of the door frame, a third temperature sensor arranged at a metal plate of the hidden door handle, a fourth temperature sensor arranged in the hidden door handle, a first heating wire arranged in the rubber sleeve of the door frame, a second heating wire arranged at the metal plate of the door frame, a third heating wire arranged at the metal plate of the hidden door handle, a fourth heating wire arranged in the hidden door handle, a vehicle door controller, a vehicle body controller, an IVI entertainment host, a T-BOX and a vehicle power supply controller; the vehicle door controller simultaneously collects temperatures of the first temperature sensor, the second temperature sensor, the third temperature sensor and the fourth temperature sensor, controls the first heating wire, the second heating wire, the third heating wire and the fourth heating wire according to the collected temperatures, and communicates with the vehicle body controller, the IVI entertainment host, the T-BOX and the vehicle power supply controller through an automobile bus.

[0026] The application has the following advantages:

[0027] 1) The application introduces temperature sensors and heating wires to cooperate with a vehicle door controller to control temperature, and cooperates with a BCM controller, an IVI entertainment host and a T-BOX to realize the ice breaking function of the vehicle door and the hidden door handle in multiple ways, the ice breaking process is elegant, does not have noise and mechanical deformation, does not increase the weight of the vehicle door, and has small installation space;
